3 Claims.

This invention relates to new and useful im provements in scaffolding ofa demountable nature capable of being used for various purposes such asin hallways, on stairways, in classrooms, etc.

An important object of the invention is to provide a suspended walkwayadapted for supporting boards or planks according to the weight to besupported.

Another important object is to provide a demountable structure of thecharacter stated including a safety saddle which is capable of beingeasily handled.

Still another important object of the invention is to provide astructure of the character stated which is of simple and sturdyconstruction and specially constructed to eliminate bending or springingof the supporting boards or planks.

Other objects or" the invention reside in the ability of this device tobe placed in narrow passageways and easily handled either in pieces orin assembled form.

A further object of the invention is to provide such a scaffoldingstructure that will materially reduce the expense of setting upscaffolding, in that boards or light Weight supporting members can beemployed instead of heavy planks in order to maintain the assembly at alow weight.

In the drawings:

Figure l represents a side elevational View of the present inventioninstalled on a trestle.

Figure 2 is a top plan view of the structure shown in Figure l.

Figure 3 is an end elevational View.

Figure 4 is an enlarged sectional View taken substantially on the line4--4 of Figure l.

Figure 5 is a perspective view of the saddle.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 generally refers to a conventional type oftrestle including a beam 6 supported at its ends by upwardly converginglegs l, between each pair of which is a spreader 8 with a brace 9extending therefrom and connected by suitable clamp means Ill to aninner position on the beam 6.

In carrying out the present invention, a pair of saddles, such as isgenerally referred to by numeral II in Figure 5, is employed, one ateach end portion of the beam 6.

Each saddle structure Il comprises an elongated strip I2 of metal, theintermediate portion of which is adapted to rest upon the upper edge ofthe beam 6. The strip I2 is bent downwardly at its ends, as at I3, andthen backwardly, as at I4, these end portions of the strip l2 havingfoot portions I5 which are Welded to inclined portions I6 of bracketsI'I, these brackets having vertically disposed spaced portions forsnugly hugging the sides of the beam 6, as suggested in Figure 4. Theupper ends of the inclined portions I6 of the brackets I'I are disposedhorizontally, as at I8, and as is shown in Figure 5, openings Ill areformed in the end portions of the strip I2, the portions I8 of thebrackets I'I and the portions I4 of the strip I2 in order to receive abolt member 2D which depends from a clamp plate 2l located above thestrip` I2. The lower end of this bolt member 2U is provided with a wingnut 22.

As can be seen in Figure 4, the purpose of the clamp plate 2| is toclamp stage boards 23, 23 in place upon the saddles II. Certain of theclamp plates 2l are provided with upstanding posts 24 which are bridgedby a guard rail 25.

It can be seen that with the parts thus constructed, they can be readilyassembled and the entire structure erected or demounted for the purposeof placement for use in a very short amount of time.

Furthermore, this structure is the only one of its kind which provides afirm hand rail that increases its safety and eiiciency 100%.

While the foregoing specification sets forth the invention in specil'lcterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to Without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

l. A scaffolding of the character described comprising a trestle havinga horizontal beam, a saddle structure on each end of the beam disposedtransversely of the beam, stage planks disposed longitudinally of thebeam and upon the saddles, and retaining means for the stage boards,said retaining means comprising clamp plates disposed over certain edgesof the boards and bolt members extending downwardly from the clampplates and through end portions of the saddle structures, and a guardrail structure rising from the clamp plates at one side edge of one ofthe boards.

2. A scaiolding of the character described comprising a trestle having ahorizontal beam, a saddle structure on each end of the beam disposedtransversely of the beam, stage planks disposed longitudinally of thebeam and upon the saddles, and retaining means for the stage boards,said saddle structures each comprising a pair of closely spaceddepending brackets for snugly engaging opposite sides of the beam.

3. A platform support comprising a pair of saddle structures, each ofsaid saddle structures consisting of a horizontal member and a pair ofbracket members depending from said horizontal member, said horizontalmember being adapted to support a platform, said bracket members beingadapted to engage opposite sides of a beam, and box-like formations atthe ends of the saddle structures through which platform fastening meansare disposed.
